This course provides a nontechnical, in-depth treatment of recent fintech developments for those aiming to work in finance. We will focus on three widely discussed fintech topics: blockchain and cryptocurrencies; crowdfunding and P2P lending; and high frequency trading. Specifically, we will learn what those technologies are, stylized facts on how they are used in practice, and the pros and the cons of applying those technologies to financial markets. Our discussions will be grounded in recent empirical findings and theories from economic literature and will focus on the main regulatory problems that arise due to the technologies. Students may be asked to complete readings prior to class and will be expected to participate in class discussions.
